Which is true regarding Enterprise Manager monitoring and configuration?
A.
Agents must be deployed on the- storage servers, in case all the database servers are down.
B.
Monitoring the power distribution units (PDUs) is done by Enterprise Manager agents, but
additional ethernet cables are required to connect the PDUs to the internal network switch in the
Database Machine
C.
Monitoring the power distribution units (PDUs) is done by Enterprise Manager agents without,
any additional network configuration.
D.
Agents may be deployed on the storage servers, in case all the database servers are down.
E.
Monitoring the power distribution units (PDUS) is done by Enterprise Manager agents but
additional ethernet cables are required to connect the PDUs to the corporate network switch.
Explanation:
Note:
*The following prerequisites must be met before you can deploy the plug-in:
Set and validate the preferred credentials on all Agents where you want to deploy the plug-in. This
is essential in order to deploy the plug-in.
The PDU firmware version must be 1.02 or later.
*This plug-in will be used to monitor PDU’s actual current value of Phase1, Phase2, and Phase3
and raises appropriate events if they have crossed the different threshold values. Each PDU will
have a plug-in instance added to its own OEM Grid Control agent.
By deploying the plug-in to your Grid Control environment, you gain the following management
features:
Monitor PDU targets.
Raise alerts and violations based on thresholds set on monitoring and configuration data.
Provide rich out-of-box metrics and reports based on the gather

Power Distribution Unit
Should be B
During a standard deployment the PDU’s are connected to the Exadata management network. The Exadata management network is used to connect all Exadata components to your existing management network. For example your ILOM, switches and also your PDU’s to the management network.
A is wrong. Agent is on DB node only
B is wrong. No additinal cable required
C is right. EM agent monitor via management network without additional cable
D is wrong. no agent deployment on storage server
E is wrong. no connection from PDU to corporate network switch
So C is correct
I guess the correct answer should be E:
To remotely monitor the PDUs, connect each PDU to the management network. PDUs should be connected with an Ethernet network cable directly to a data center switch,
The answer B says:
C?
Configuring the PDU as defined in MOS note PDU Threshold Settings for Oracle Exadata Database Machine (Doc ID 1299851.1) will cause the PDU to send alerts via SNMP with will be picked up and displayed in the Enterprise Manager Plugin. No addition configuration of alerts is needed in Enterprise Manager.
